CA42/50/52 Introduction and safety summary Chapter 1

1.1 Introduction and system familiarization

Congratulations on your purchase of SIMRAD CA42/50/52 DGPS ChartRadar with Echosounder - a combination of the latest GPS

receiver technology with built-in differential receiver for accurate positioning and prepared for SDGPS, plus: detailed cartography and high performance radar and echosounder technology; all in a unique slim-line design with a 10” ATFT (CA42), 14” TFT (CA50), or 15” TFT (CA52) large LCD display in color.

The CA42/50/52 chart system includes a built-in world chart for rough planning and overview. The choice of chart system best suitable for the CA42/50/52 was carefully singled out to be the C-MAP NT+ mini cards. The optional C-MAP cards are available world-wide at your local Simrad dealer.

The echosounder system with selectable frequencies will provide an impression of Bottom expansion, VRM expansion, A-scope and white line.

The radar system with dual EBL and VRM markers, direct Quickrange keys, off-center mode, etc. together with Dual radar feature … two radar displays in one screen, one for short range and one for long distance observations.

The Global Positioning System is at this time and age the most common system used for navigation and positioning all over the world. Not only for maritime use, but also for land-based applications and aviation. The satellite-based system has been developed and is operated by the US Department of Defense in order to provide an accurate and reliable service, which include a 24-hour global coverage. The GPS system consists of approx. 24 satellites which orbit around the Earth at an altitude of approx. 20,200 km. The satellites transmit perfectly synchronized data. However, depending on the position, the signals will reach the receiver at a slightly different time. By adding the measured time difference to the known position of the satellites it is possible to calculate the ship’s position to within a few meters.

CA42/50/52 Introduction and safety summary Chapter 1

DS42/50/52 Dual Station for the CA42/50/52 is available in 10” ATFT color, 14” TFT color and 15” TFT color.

How to use this manual? The manual is written for the products: CA42, CA50 and CA52, which all share the same type of software. From hereon, these models are referred to as: CAXX. It is a good idea if you make yourself familiar with the key functions, menu structure and rotation of pages (screens) described in chapter 2 before you start out, and then proceed with section 2.7 Initial start-up. For quick location of a certain term, please check the “Glossary of terms” and the “Index” at the back of the manual. How to interpret special marked key symbols, etc. in the manual:

+/-

Either the + (plus) or – (minus) key may be applied.

0-9

Alpha-numeric keys for insertion of figures.

to obtain what is

written in italic next to the keys.

1.2 Safety summar y

Precaution The operating unit should not be exposed to direct sunlight, as “boiling” the display may cause too high temperatures internally and subsequently damage parts of the unit beyond repair.

Power source, fuse and power cable Check that the DC power supplied to the unit is within the range of 10 to 32 volts. Note that the appropriate fuse must be employed (F6.3A). Ensure that the power cord is firmly attached.

Grounding To reduce electrical interference and risk of electrical shock, properly ground the unit to the ship’s ground using the ground screw on the back of the unit. Good grounding should also be exercised for connected equipment, refer to separate Installation manual.

CA42/50/52 Fundamentals & initial start-up Chapter 2

2.1 Fundamentals of the PAGE and WINdow system

The CAXX DGPS ChartRadar with Echosounder has a multi-function screen data presentation system. You can choose to have a full screen, or a screen divided into e.g. a chart display and two data/chart displays, etc. The current active display is indicated by a highlighted frame around the active window. There are five screen combinations to choose from:

WINdow 0

1. Full (1/1) screen. 2. Four ¼ displays. 3. Two ½ displays.

4. & 5. Combination displays of one ½ and two ¼ displays shown together in the same screen. ) Not all displays are available in any size windows.

CA42/50/52 Fundamentals & initial start-up Chapter 2

As many as 4 screen combinations or full screens can be saved in 4 pages (layers).

Press the

[PAGE] key to toggle between the 4

pages, or hold the [

PAGE] key depressed for

two seconds to start a rotation of the 4 pages. Press [

PAGE]

again to return to manual

operation.

To mix and match the various chart and data displays you wish to have in the PAGE and WINdows presentation, you will first need to know what is pre-set from the factory:

PAGE

Scroll through the four pre-set pages to see if you wish to exchange any of the displays with a different one.

Example of how to edit a pre-set page:

window

We pretend that in this page, window 2 contains the navigation display (highway), window 3 a chart display in a large scale for overview, and window 5 a chart display in a smaller scale to enlarge a

certain area. You now wish to insert the Position display in window 3 instead of the chart display. This is the procedure:

WIN

Press the

[WIN]

key until the frame around window 3 is highlighted

Call up the menu bar, and…

2,1

then call up the POS menu and select “Position”

- you will now have the Position display in window 3 instead of the chart display.

Example of how to edit a full screen to four ¼ displays:

We pretend that you are looking at a full screen which you wish to divide into four ¼ displays. This is the procedure:

MENU First call up the menu bar, and…

then call up the POS menu - see example next page.

CA42/50/52 Fundamentals & initial start-up Chapter 2

POSITION

WIN

_2_

POS _1_ Position _2_ Dual speed

_3_ Speed, course & depth

etc.

What you do now will determine which WINdow the display you are about to select will appear in.

Press the

[WIN]

key repeatedly to scroll

through the window system.

WIN

Press the [WIN] key once to select WINdow 1

-which is the left top quarter of the screen.

Select the Position display

- you will now have the position display presented in window 1. The rest of the windows in this page i.e. window 2, 3 and 4 will contain the displays which were pre-set from the factory. They can all be exchanged with new displays at your choice.

) However, the same display can not appear twice on the same page, so in case you are trying to select the same display in a second window, this is what will happen:

As per above example, you have selected the Position display in window 1, but it may just happen that the Position display was pre-set to window 2 – therefore window 2 will now show the legend: “ Select display via MENU.”

You may select the same display to appear on different pages, but not on the same page.

) An exception is the radar display, which only can appear in ½ window or full screen, and you can only have the radar display appear in one page at a time. You can not toggle from page to page and see different radar displays.

CA42/50/52 Chart menus and INFO windows Chapter 3

All user data in the chart system are listed under ‘Chart settings’ in the display example and are described below:

Chart can be set to

NORMAL, COMPRESSED and CHART OFF:

NORMAL

- will automatically select the chart level appropriate for the selected

range/scale.

COMPRESSED

- will change the range (scale) / chart level ratio one step, which,

depending on the actual chart, will select a more detailed level.

CHART OFF - will only show all the user-made data such as waypoints, routes,

lines and tracks, etc.

Boundary lines will indicate available C-MAP chart areas.

Mixing levels – when set to ON you will no longer see any blank chart areas, as

the C-MAP library will find the missing area in a different level to cover the blank area otherwise left on the screen. However, when using this feature, chart re-draw time will be increased a little.

Marine presentation can be set to INTERNATIONAL or AMERICAN: INTERNATIONAL – will present NavAids in ‘real life’ shapes and colors for quick visual recognition (as per official INT1 standard paper chart presentation). AMERICAN – will present NavAids in simplified shapes and real colors (as generally found on NOAA paper charts).

Simplified draw mode – when set to ON the NavAids will be shown in generic symbols for minimum visual clutter on-screen.

Quick chart info – placing the chart cursor on a C-MAP object will activate a small info window with details on the object. Info window will automatically close after 10 seconds or when cursor is moved away.

Chart area can be set to

SMALL, MEDIUMorLARGE.

SMALL

– Opens a small chart area big enough to just fill the size of the screen.

When panning and scrolling, the chart will automatically be redrawn.

MEDIUM

– Opens a medium-size chart area for pan and scroll which goes beyond

the size of the screen. The chart redraw time increases equally.

LARGE

– Opens a large chart area for pan and scroll in a size which goes well

beyond the size of the screen. The chart redraw time increases equally.

Orientation can be set to

NORTH UP, HEAD UPorNAV UP

, and the mode can be

RELATIVE or TRUE motion. NORTH UP

– The chart will always be presented as north up.

HEAD UP – The chart will automatically turn, so your actual course (COG) is up.

If a compass is connected, the reference will automatically change to heading (compass).

NAV UP

– The chart will automatically turn, so your bearing to destination is up.

) To enable chart rotation the chart cursor must be turned off [CLR].

TRUE

motion – The ‘ship’ will move across the chart.

RELATIVE motion – (‘Chart area’ will default to MEDIUM). The ‘ship’ is locked

to the center of the screen and the chart will move.

Rotation resolution can be set to adjust the chart for each 5, 10, 15, 20 or 25° changes in present course or heading.

Depth–Level1,2and3 are identified by different colors. The number of meters in the levels can be changed. The colors are preset, see section 10.6.

Grid the LAT/LON grid can be set AUTO/ON/OFF. The color of the grid is preset in Palette setup, section 10.6.

Show range ON will add a small line to the chart display indicating that the length of the line equals a certain number of nautical miles/km.

Auto chart select When sailing with “Auto chart select” ON and cursor turned OFF, the scale will automatically change to the chart which is available. But when set to OFF, then the selected scale will remain, also when sailing “out of the chart”.

Extended level range ON will enable changing range 3-4 steps within the same chart level after having selected the range via a numeric key.

With built-in or connected DGPS receiver: dGPS= differential data received. DGPS= differential data received and used for corrections. SDGPS= satellite differential data received and used for corrections.

Status indicator and accuracy

Small letters (a,b,c,) indicate that SA is active, and the position accuracy is expected to be better than 100 meters in 95% of the time. Capital letters indicate that SA is OFF, and the position accuracy is then expected to be 15 meters or better in 95% of the time. dGPS indicates that differential data is received, either via built-in differential receiver or from external receiver. DGPS or SDGPS indicates that the position is corrected by the differential data. The accuracy will typically be 1-3 meters for DGPS and 2-6 meters for SDGPS.

In order to utilize the high accuracy of the GPS system, it is necessary to align the lat/long calculations to the paper charts you are using. RefertoPositionsetupdisplayonnextpage. ) When using C-MAP electronic charts, the datum will be aligned automatically.

The value of HDOP

(horizontal dilution of precision)

expresses “the quality” of the satellite geometry in relation to 2D positioning and a fixed antenna altitude.

PDOP (position dilution of precision) is equivalent to 3D positioning. The values will typically stay between 1.3 and 8. The lower the value the higher the “quality”. A poor geometry might produce a value of more than 20.

If the preset DOP limit is exceeded (indicated by * in the position display) it will cause the position updating to stop until it once again is within the limit.

The DOP limit can be changed manually, but should not be set higher than 8 (factory setup), as this may result in poor accuracy – false position.

LOCKED = locked on a beacon and receiving differential data

NOT LOCKED =

not locked on a beacon and receiving no differential

data.

NOT INSTALLED = there is no built-in DGPS module in unit. NOT IN USE

= external DGPS receiver applied.

YES

it should be safe to rely on the received differential data, because the beacon station’s performance is under observation. If

, then you have to use the received differential data with caution,

as there is no guarantee it is not faulty.

Frequency – the frequency of the beacon station can be set manually if known. However, when left in

AUTO

the navigator will always search

for the nearest station with a good signal strength.

Bit rate – indicates bits per second, and can be set manually to 25, 50, 100 or 200 bps.

Signal strength – a good signal strength is 20 and up.

Signal to noise ratio (SNR) – should be 8dB and up.

CHANNEL 1: sat.no. - indicates which satellite number and name is currently tracked/searched by channel 1, and what is the tracking state see also section 4.7.1.

Corrections - indicates if corrections are being received on this channel. If YES: is the quality of the reception sufficiently high for the corrections to be usable.

NONE: no corrections are received. RECEIVED: corrections are received, but of insufficient quality. USABLE: corrections are received and of sufficient quality. USED: corrections received on this channel are used in the position

determination.

Integrity messages ok - the SDGPS system will transmit messages concerning the integrity of the GPS satellites. This line will indicate whether such messages are received and reliable.

Range used for position fix - if the receiver is tracking a particular SDGPS satellite, it “knows” the distance to that satellite. This line will indicate whether the distance is used in the position determination.

Type 0 warning received - if an SDGPS satellite is not operating according to specifications it will transmit a so-called “Type 0 warning”. In this situation, the receiver will not use any information that it might receive from that satellite. Until the SDGPS system is declared operational, the SDGPS satellites will always transmit Type 0 warnings. ) It is possible (but not recommendable) to override the Type 0 warnings - refer to last line in SDGPS setup.

CA42/50/52 Echosounder operation Chapter 7

7. Echosounder operation

The echosounder function of the CAXX determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source. Thus by calculating the time difference between the transmission of a sound wave and the reception of the reflected sound wave, the depth to the object can be determined.

The entire process begins in the display unit. Transmitter power is sent to the transducer as a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any reflected signals from intervening objects (such as a fish school) are received by the transducer and converted back into an electrical signal. It is then amplified in the amplifier section, and finally, displayed on the screen.

The picture displayed is made up of a series of vertical scan lines (pings), one for each transmission. Each line represents a ‘snapshot’ of what has occurred beneath the boat. The series of snapshots are accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are displayed.

Selecting echosounder displays

The CAXX provides four types of echosounder displays: standard, bottom zoom, marker zoom and A-scope. Each display has its advantages and disadvantages. Select the appropriate setup for the echosounder display in the presentation ‘Setup’ and ‘Echosounder setup’ displays, considering current sea area and target fish.

) To view the echo display while plotting ship’s route, select a CHART display in one window and an ECHO display in the adjacent window.

7.10 How the echosounder works

When the CAXX is turned on, the processor begins to send electrical pulses to the transducer. The ceramic resonators in the transducer has a special property which enables it to change dimensions slightly when a varying voltage is applied. The voltage is thus converted to mechanical vibrations (sound waves) which are then transmitted down through the water. See Fig. 1.

The sound waves move through the water until they encounter a change in density, such as a fish or the bottom. This causes the sound waves to “echo” back up through the water. When the reflected sound waves (echoes) hit the transducer, the ceramic disk vibrates at the same frequency. This generates a varying voltage between the disk surfaces. This voltage goes back up through the cable to the receiver. The CAXX processes the signals and presents them on the display screen. See Fig. 2.

Fig. 2 – Echo returning to the receiver.

7.11 Transducer beamwidth

The transducer mounted to the hull of your vessel serves as both a “speaker” when transmitting, and as a “microphone” when the echo- sounder is receiving. Similar to the way a flashlight focuses light, most of the sound from your transducer is focused downwards with a smaller amount going out to the sides. The amount of focusing of the sound beam is expressed as a “beamwidth”.

The center of the sound beam is the most intense, then as you move out towards the sides of the sound beam there is a point where the intensity of the sound is half what it was in the center. The distance moved is the “beamwidth”.SeeFigure3.

7.12 Effects of the vessel’s speed

The display of fish on the CAXX depends directly on the vessel’s speed, as well as on the depth of the fish. When the vessel is at rest, the echo traces will appear stretched and flattened. As the vessel’sspeed becomes greater, the echo traces will become shorter and more arched. The reason for this change in appearance is that as the vessel speed increases fewer number of sound “pings” strike each fish. A low vessel speed will provide the most accurate information of where fish are located.

The CAXX combines chart plotting with radar navigation. For first time users of Radar, we have included a basic description of the radar presentation with a basic understanding of how the controls affect the radar’s operation and display.

The following paragraphs describe the control settings used for initial display setup, turn-on procedure, inclement weather operation and finally the turn off procedure. Radar controls are described in chapter

8.2.

8.1 Radar map

The radar picture appearing on the display is a map-like representation of the area in which the radar is operating. Typically, the ship’s position is at the center of the display. The operator may reposition or offset the ship’s position up to 66% of the radius anywhere on the screen. The ship’s dead ahead bearing is indicated by the heading line flashing at the 0° relative bearing with every revolution of the sweep trace (Head-Up mode).

Coastline contours and landmass are generally depicted in solid filled yellow (DAY) or green (NIGHT) echo areas. Other surface vessels, and channel buoys, are displayed as smaller single “pips” or echoes. The radar picture or map can be viewed in many different sizes or scales from own ship. These sizes are selected by the range scale controls. Greater detail of radar echoes nearby own ship is shown when the short or nearby range scales are selected. The best technique for assessing the radar presentation characteristics is to start with using a longer range scale and then switching to shorter ranges when nearby targets appear, or as the ship approaches the coastline, harbor, or other vessels in the area.

The long range scales (i.e. 3, 6, 12, 24nm) best show the overview of the ship’s relationship to landmasses, weather fronts, and large ship targets at or beyond view.

8.1.1 Map orientation

In the RELATIVE mode, the heading line always appears on the screen at 0° relative according to the on-screen bearing scale, and is coincident with the antenna beam passing the ship’s bow. Thus the top of the displayed picture represents the direction in which the ship is heading.

All targets appearing on the display are “Relative” to own ship’s position and heading. As you look outside at targets around you, you will see that the targets are appearing on the Radar display at the same relative bearing.

The Electronic Bearing Lines (EBL) are available radar tools used to measure bearings to radar targets from own ship. The bearing readouts maybeinrelativeortruemodes.

8.1.2 Environmental effects

The effects of weather and water surface conditions generally act to reduce the ability of radar to detect targets. Weather effects reduce the long range at which targets can be detected. Water surface clutter (waves) reduces the ability to detect targets close by. Either can obscure the echoes from targets that may prove dangerous to your vessel.

You can’tseewind on your radar screen, however you can see its effects when it produces waves and spray on the water surface. “Sea Return” is most pronounced in the direction from which the wind is blowing. Proper use of your “Sea clutter” (also known as STC) adjustment can reduce the effect of wind and waves, but care must be taken not to increase the control to the point where weak targets will be overlooked.

Rain, hail and snow can return echoes that appear on your radar screen as a blurred or cluttered area. Targets within the area of precipitation can be masked by the clutter. The maximum range of the radar pulse is greatly reduced as the energy of the radar beam is scattered and absorbed by the water droplets. Proper use of your Rain Clutter (also known as FTC) adjustment helps you to look into areas of precipitation to detect targets.

Buoys are moored to the bottom with concrete via chain. The chain is longer than the depth of the water to allow the buoys to ride in the current and go up and down with the tide. Unfortunately this allows the buoys to lean in the direction of the current. Radar reflectors built into the buoy do not work well when the side of the buoy is pointed to the sky. Therefore if you are going with the current, the images of the channel markers may appear faint. If you are going against the current, the buoys will be leaning in your direction and produce a stronger image on the radar screen.

The iron mass and angles of the metal in the structure of a bridge can cause unpredictable interference patterns on your radar. It is not unusual for a reflected image to appear on the radar screen in front of you just as you pass under the bridge. A similar effect is also common on sailboats where the radar antenna is mounted close to an aluminum mast.

Overhead cable crossings can mimic a moving target on your radar screen. The cable target usually appears to be on a collision course. The entire length of cable does not appear on the screen, only a point on the cable, and that point keeps changing giving the illusion of a moving target.

8.1.3 Effects of ship’s movement

Radar images can be drawn in two ways on the radar display to show the ship’s motion. The type of display modes are called “Relative motion” and “True motion”. In Relative motion, the most common radar display mode, own ship is permanently fixed at the center of the display but radar echoes (targets) move in relation to your vessel. With no movement of the ship, a steady display of fixed radar echoes is shown. If the ship is moving ahead on a constant course, echoes appearing at the top of the display will move downward across the display. Your own ship’s position will always remain at the center of the display.

If the vessel alters course to the right, the displayed echoes will be displaced by an equal amount in bearing in a counterclockwise direction, and vice versa. These changes in the display pattern with ship movement is an extremely important characteristic to remember

when maneuvering around nearby vessels, or buoys. The True motion display mode can be compared to your vessel moving on a map or chart. In True motion mode, the surrounding landmass echoes remain stationary on the screen and if your ship is moving at a constant course and speed, you will see your position move across the screen towards the edge of the display. Any other targets which are underway will also be moving on the display screen at their True course and True speed. All motion seen on the True motion display is “TRUE” (meaning motion over the ground).

8.1.4 Navigational echoes

Echoes displayed on the radar screen may be large or small, bright or faint, depending on the size and shape of the object and its angle relative to your radar antenna. The radar indication is not always the same as an observer’s visual indication; a nearby small object may appear to be the same size as a distant large object on the radar. With experience, however, different targets can be identified by the relative size, brightness, and position of their radar echo returns.

Buoys and small boats are one example of targets that are sometimes difficult to distinguish from each other. Their movement in the waves do not present a consistent reflecting surface. Consequently, their echoes have a tendency to fade and brighten or sometimes to disappear momentarily. Although buoys and small boats often resemble each other, usually the motion of one target identifies the boat from the buoy.

High coastlines and mountainous coastal regions are often observed at the longest ranges of the radar. However, the first sight of landfill on the radar’s longest ranges may be a mountain several miles inland from the coastline and not the actual coastline. The coastline may not appear on the radar until the vessel has approached land nearer the line of sight distance.

8.1.5 Sea return

Not all radar echoes are produced by hard navigation items such as boats, buoys and land. Some radar echoes may be received from irregularities on the surface of the water, particularly at close range by
